RUVA typically refers to the "Recycled Used Vehicle Association," an organization focused on promoting sustainability in the automotive industry through the recycling and reuse of vehicles. It aims to enhance the environmental benefits of recycling vehicles and to provide resources and advocacy for businesses involved in the used vehicle market. The association often works on initiatives related to vehicle recycling standards, best practices, and industry education. However, the acronym could also refer to different organizations or concepts depending on the context.

They are actually two different type of beds. Wolf beds are more like natural sun, therefore maybe more damaging to your skin. Ruva beds are less likely to burn your skin, however, you may not get as much color from 1 session as you would in a Wolf bed. My preference is an Ultra Ruva-which will emit a small amount of both UVA and UVB ray.
